Dodge Viper 2004-2010 Key Programming Procedure
The following are the key programming procedures for Dodge Viper for the year 2004, 2005, 2006, 2007 and 2010.
ADD KEY (Must have two working Sentry Keys):
1. Put one of the two current keys into the ignition and turn to the ON position.
2. After the key has been in the ON position for at least three seconds — but no more than 15 seconds — turn the key back to the OFF position.
3. Take the key out and put in the second current key, turning it to the ON position, all within 15 seconds. The second key cannot be the same as the first key.
4. After ten seconds, a theft alarm light will illuminate and a single chime will sound. This confirms entry into “Customer Programming Mode”.
5. Within 60 seconds, turn key OFF and remove the current key.
6. Put a new key into the ignition and turn to the ON position.
7. After ten seconds, a single chime will sound. The theft alarm light will turn off. Wait three seconds and turn key OFF.
8. Repeat these steps for additional keys.
About Dodge Viper
The power output was increased to 592 to 600 horsepower (441 to 447 kW; 600 to 608 PS) at 6,100 rpm and 560 lbft (759 Nm) of torque at 5,000 rpm with the introduction of the 8,382 cc (8.4 L; 511.5 cu in) V10 engine in 2008. The engine also received better flowing heads with larger valves, MECADYNE cam-in-cam variable valve timing on the exhaust cam lobes, and dual electronic throttle bodies. Due to improved valvetrain stability from both the new camshaft profiles and valve springs, the rev limit could be increased by 300 rpm. McLaren Automotive and Ricardo Consulting Engineers provided some external support in the development of the engine. Continental AG created an electronic engine control that can monitor the crankshaft and cylinder position up to six times during each firing and has ten times the processing power of the prior unit.
Outside of the engine, changes were less drastic, although the vented engine cover distinguishes the third and fourth generations of the Viper. The Tremec T56 transmission was replaced with the Tremec TR6060 transmission, which features triple first-gear synchronizers and doubles for higher ratios. The GKN ViscoLok speed-sensing limited-slip differential was added to the Dana M44-4 rear axle from 2003 to 2006, substantially assisting the tires in gaining grip under acceleration. The removal of run-flat tires improved grip and driver feedback, while the new Michelin Pilot Sport 2 tires, together with updated suspension (springs, anti-roll bars, and shock valving), made the Viper more neutral in corners.
Another notable change was the reworked exhaust system; previous third-generation cars had their exhaust crossover under the seats, resulting in a significant amount of heat entering the cockpit, which was done initially to help improve the car’s exhaust note, as the first two generations of the Viper, which had no crossover, were criticized for their lackluster exhaust notes. The car now had a redesigned exhaust system with no crossover, which reduced the amount of heat that got into the cabin.
For 2008, the electrical system was entirely overhauled. A 180-amp alternator, twin electric cooling fans, electronic throttles, and a completely new VENOM engine control system were among the modifications. To ensure regulatory compliance, the CAN bus design was merged with pre-existing systems. A higher-capacity gasoline pump and filtration system were added to the fuel system.
The Viper ACR made a comeback for the ZB II generation, and it was put to the test at the Nürburgring, where it set a new lap record of 7:22.1. On Monday, April 11, Kuno Wittmer set a new lap record of 1:59.995 in a street legal 2010 Dodge Viper ACR at Miller Motorsports Park in Tooele, Utah, breaking the 2-minute barrier for the first time in a production car on the 3.048-mile Outer Course circuit.
